Cells Flashcards
What are the 5 glial cells
Schwann cells, oligodendrocyte, microgloa, astrocyte, ependymal cells
What does Neuroglia mean
Cells that act as nerve glue
What are the two myelinating cells
Schwann cells and oligodendrocytes
Where would you find Schwann cells
In the periphery nervous system
What do Schwann cell myelinate
Signal neuronal axons
How much of an axon does a Schwann cell cover
1mm of axon
Where do you find oligodendrocytes
In the central nervous system
What do oligodendrocyte myelinate
They have different processes and myelinate sections of different neuronal axon
Other then myelinating, what else do oligodendrocytes do
Provide 3D support
What are the supporting Glial cells
Astrocytes and microglia
Why are astrocytes so distinctive
They’re shaped like stars
What do Schwann cells look like
Trees on their side
What do oligodendrocytes look like

What area of the body do astrocytes support
The brain and other parts of the body
What kind of synapses do astrocytes process
Envelope synapses
What do astrocytes act as a reserve for
Fuel source
How are astrocytes involved with blood
The arms connect to blood vessels and regulate blood flow
What NS would you find astrocytes
The CNS
What NS would you find microglia
CNS
What do microglia look like
Loads of trees from a big seed
How many sub types do microglia have
9
What is microglia’s primary function
Protection
Microglia are capable of rapid…
Proliferation
What is the most immune responsive glial call
Microglia
What does microglia clear
Debris
Where do you find ependymal cells
Spinal cord and ventricles
What do ependymal cells look like
Squares with hair
What do ependymal cells form
Ependyma- tissue lining
What do ependymal cells produce and regulate
Cerebrospinal fluid
What other glial cell does the basal membrane of ependymal cells attach to
Astrocytes
What is “nerve glue” called
Neuroglia
What glial cell would you find in the periphery
The Schwann cell
What glial cells do you find in the CNS
Oligodendrocytes, microglia & astrocytes
What glial cells act like a fuel source
Astrocytes
What glial cell is involved in blood
Astrocytes
What glial cell can rapidly proliferate
Microglia
What is it called when a cell can rapidly multiply
Proliferation
What glial cell would you find in the spinal cord and ventricles
Ependymal
What cell produces and regulates cerebrospinal fluid
Ependymal cells
What part of its self does a ependymal cell use to attach to astrocytes
Basal membrane
